Adjust the thickness of the bean grinder for a few moments-hario manual bean mill

When adjusting the electronic bean mill, we should first grasp the relationship between the amount of powder and the degree of grinding. Thinking that these two variables change with the change of one variable, we need to constantly adjust the test in order to achieve the best results.

Every small change in the bean grinder will have a great impact on the overall quality of the coffee. Therefore, as a barista, you should re-measure and adjust the bean grinder every day to ensure the perfect quality of the coffee.

To master the gouache ratio, you can use a constant amount of coffee powder (for example, 18 grams) in the exercise, try to match different total coffee weight, and then compare the differences in taste, purity and mellowness. You need to decide the final gouache ratio according to your personal preference. The hardest part of the electronic bean grinder is that when you adjust the grinding parameters, the distance between the knives will change accordingly, and the change in this distance will directly affect the flour output of the bean grinder, that is, the time of grinding and milling. If you want to make the grinding degree finer, the distance between the sharpening knives will become closer, and there will be fewer coffee beans passing through the sharpening knife at the same time. On the contrary, the distance between the sharpening knives becomes larger, and the coffee beans that pass through the sharpening knife will become more in the same time. The debugging of the electronic bean grinder is mainly aimed at two variables, the amount of powder and the degree of grinding. These two variables are mutual, and if you change one of them, the other will also change.

The ordinary electronic bean grinder adjusts the grinding and pulverizing time of the bean mill according to the pre-set amount of powder (please note that the amount of powder is adjusted by the mill based on time rather than weight). If you are not satisfied with the quality of your coffee, the first thing you need to do is to determine whether there is a problem with the amount of powder or the degree of grinding.

In general, the distance between the correct weight, flattened and powdered pressed powder and the outlet should be 5-6 mm. If the height of pressed powder is not in this range, you should try to adjust the powder output of the bean mill (that is, grinding and pulverizing time). When adjusting the amount of powder, the range of each adjustment should be between 0.2 and 0.3 seconds. After each adjustment, you need to re-test the quality of the coffee.
